Plus one of the benefits you'll be interacting with lots of people - sellers and buyers and may by chance come across your future partner to jointly buy MFH.  

One benefit for me is it allowed me to buy a newer property in a great area with top schools, where a SFR in the same area was beyond my budget. 

However, there do seem to be solid benefits as well. 

I am currently gaining my license and looking to join a team to be a strong asset while learning and growing.

We are looking to flip, gain rentals, do rehab work.

What are the tax benefits?

Question: Should I sell my current home and use the capital gains to purchase higher cash-flowing properties or use it as a buy and hold?

But in my experience, having owned both for decades, is that tenants of small multifamily properties are oftentimes more transient (meaning higher turnover than in SFR) which tends to negate some of the efficiencies that you gain. 

Theres a dozen ways to make money in real estate and theres a dozen way for each one of those to have an advantage gained through college. 

You can find the exact chart if you google "Texas veteran real estate benefits" but if you have a disability rating you can be exempt from paying a certain amount of money (thousands) in property taxes.
